Very rare item for your gas and oil collection!! Vintage PENETRATING OIL formerly sold as “GRAPHO PEN-A-TRATE” and “A.B. CROSS TTT JOINT BREAKER”. Not sure where this company was located and have not found another one of these listed anywhere. Very good overall condition with no chips or cracks to the empty Temperglas bottle. Plastic lid unscrews as normal. Paper labels front and back are intact with some wear from age and handling as shown. Wrinkle to front label. Bottle measures about 6 7/8” high. See pics for more details.
